General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE46F6510 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
With such manifestations, the BN44-00623B power module usually fails. It is necessary to measure its output supply voltage, and in case of their absence, check the serviceability of the power switches (STF13NM60) of the converters and rectifier diodes for the possibility of breakdown in PN semiconductor junctions.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short-circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWM) D2011K (Standby), SPC7011 (PFC), FSFR1800HSL, if they do not have visible damage to the case and open fault between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-01958B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Sometimes it is necessary to check or replace (if necessary) the elements of the MainBoard board - SEMS30, WT61P807, K4B2G1646E, KLM4G1FE3B, 25Q40, 25Q40, WT61P807, TAS5745. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all, check the voltage of the tuner BN40-00262B and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
It should be remembered! Attempts to self-repair a SAMSUNG UE46F6510 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

The appearance of the power supply
Main features of the SAMSUNG UE46F6510 device:
Installed matrix (LED-panel) CY-GF460CSLV2V.
The matrix control uses the Timing Controller (T-CON) BN41-01939C.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the SLC2013M PWM controller. As the power elements of the LED driver, keys of the KF9N25D type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE46F6510 TV are generated by the BN44-00623B power module or its analogs using D2011K (Standby), SPC7011 (PFC), FSFR1800HSL microchips and power switches of the STF13NM60 type.
MainBoard - the main board (motherboard) is a BN41-01958B module, using chips SEMS30, WT61P807, K4B2G1646E, KLM4G1FE3B, 25Q40, 25Q40, WT61P807, TAS5745 and others.
The tuner BN40-00262B provides the reception of television programs and tuning to channels.
